Title: Transmission
Inventor: OOSAKO ISAO
IPC: F16H61/32
Filed: 1983-03-31
Abstract: PURPOSE:To simplify a transmission in structure as well as to aim at improvements in shift operatability, by attaching a dynamo to a counter shaft, and driving or braking the latter through the former, while making the number of revolution or peripheral velocity in parts engaged with each other come congruent. CONSTITUTION:In time of shift operation, a clutch is made to come into a state of being intercepted upon stepping on a clutch pedal and under this condition, when a shift lever 28 is operated, shift directions of sleeves 10 and 11 or a gear 8 are found out at a microcomputer 21 through the output of a switch 29 which detects the selected shift position. And, the number of revolution in an internal gear 12 and a claw 13 being engaged with each other or peripheral velocity in each of gears 8 and 9 is controlled so as to be congruous. This synchronous control takes place by means of a dynamo 20 coupled with a counter shaft 14 on the basis of operation on the microcomputer 21. That is to say, the number of synchronous revolution in the counter shaft 14 is calculated in conformity with the gear ratio stored in a memory of the microcomputer 21 whereby the counter shaft 14 is driven or braked by the dynamo 20 so as to accord with this revolution.

Abstract: PURPOSE:To prevent the shock at the time of engagement in the same pressure-rising control pattern, by controlling clutch oil pressure automatically along a prescribed pattern in response to the operation of a changeover lever into a position such as ahead, neutral, astern, and trowling. CONSTITUTION:When the ahead or astern clutch 4, 6 of a marine reduction and reversing gear 2 is engaged by the operation of a changeover lever 79 for ahead/neutral/ astern/trawling, a control unit 81, first, maintains the clutch oil pressure at a slightly higher pressure P1 for a given minute time by controlling a proportional solenoid valve 73 and a changeover valve 75, and then lowers it quickly. Next, after the oil pressure has been gradually increased at an increasing rate proportional to the rotating speed of an main engine 1, it maintains the clutch oil pressure at a set pressure P2 proportional to the engine rotating speed, being slightly greater than the transmission torque at the time when the clutch has been directly coupled. Under the set pressure P2, the clutch is engaged, and after a prescribed time, the maximum pressure Pm is maintained to complete the engagement of the clutch. Thus, the engagement of the clutch can be carried out within a given time in the same pressure-rising pattern, and the shock at the time of engagement can be prevented.
